As shown below, the data the viewer displays is split into a key, labelling what the data is, and a value. What these values mean is sometimes obvious, for instance a timestamp, however they also are sometimes numeric codes without explanation of what they refer to.

Those in the Windows Insider program's Fast and Skip Ahead rings can try out the viewer by updating to build 17803.

The viewer is accessible by navigating to Settings > Privacy > Diagnostics & feedback. Enable the Diagnostic Data Viewer toggle and then click the button to launch the app. Once the app is launched, users can drill down into the data by selecting a "diagnostic event" from the left column and browsing the list of data collected.

Windows Insiders will be able to provide feedback on improvements they'd like to see to the viewer, which should be available to all Windows 10 users following the 'Redstone 4' major feature update this Spring.

Yesterday, Microsoft also announced a series of other changes aimed at improving user privacy.

The Microsoft Privacy Dashboard has a new Activity History page, which provides a clearer summary of the data saved by your Microsoft account. Upcoming changes in the "coming months" will allow Windows 10 users to view and manage data about the media they watch/listen to on their PC and add product and service activity to the Activity History page. Also in the pipeline is the ability to delete specific items of data recorded by your Microsoft account and to export any data from the dashboard.

However, Windows 10 Enterprise remains the only edition where users can virtually disable data collection by Windows 10, with Microsoft saying a base level of data collection is necessary to run Windows Update in other editions.

Alongside the Diagnostic Data Viewer, the latest Insider build of Windows 10 included various updates. Microsoft has changed the Windows Timeline feature to provide the option to delete all activities from the past hour or day and to default to only showing the past four days of activities from devices signed into your Microsoft account. Microsoft also added an extended user-mode API for third-party virtualization stacks and applications, made Windows Hello easier to set up, added an ability to turn off auto-hide on scroll bars, improved controls over which Universal Windows Program apps can access user folders, and added a new Fonts page to the Settings app.

In a post about the Insider build, Dona Sarkar, leader of the Windows Insider program, also confirmed that the forthcoming tabbed windows feature known as Sets won't be ready for the Redstone 4 update.
